Many men do brag about there penis along with anything else that they want people to think they have, mostly as 'one upmanship'.
I have met plenty guys in business that always try and 'get one over' you, whether that be their sex exploits, their car, their salary, their pension, their holiday destinations, their house or amount of houses, their wife of amount of wives, and offcourse their cock.
After a day of business, I have been at health clubs and facilities at hotels with some of these guys who have made huge bragging statements all day. As soon as you get into the locker room and start to get changed or indeed meet them at some stage of being there maybe in the pool, or in the showers afterwards, they all of a sudden become very quiet and reserved about their claims.
I have never felt the need or desire to brag, but as I have always done, I will answer when asked about my cock or any other part of my life, if asked.
I love the feeling of being hung and the reactions in people realising I am hung. We have plenty 'fun' parties with friends of a like minded feeling on sex and there is no doubt people are interested in 'dick size' and the novalty of it. Off course I turn up to these parties knowing I'm purposely showing my dick, but only because of the situation we are all in.
I haved met lots of woman over the years that I have liked to have been with, but have never even considered using the line I was hung try to promote my chances.
You get a lot of opinions from all sorts that you shouldn't brag about anything and depending on the type of people you are with will determine all what gets discussed and the nature and openess of the talk. I can be in certain groups that will openly ask and talk about sex and this usually extends into 'bragging' or is it bragging? Is it not just people comparing experiences and trying to gain the higher ground by adding an extra element to the dicussion?
I have a great partner Fiona who loves what I have and what we have together and she is always 'telling', 'bragging' about my size and our sex exploits to friends, but that is usually when she is asked or while they are in conversation about these items.
So I think people are undoubtably put off from 'bragging' by the overall general feeling to be reserved about your life.
